Abstract
The utility model relates to a ball valve with a self-adjusting valve base, which is characterized in that the valve base is arranged between a valve body internal cavity and a spherical core in a matched way, a valve base driving mechanism is arranged between the spherical core and the start-stop valve base, when the ball valve starts and stops once, the driving mechanism drives the valve base to rotate an angle towards a fixed direction, leading to a different contact position between the ball valve and the valve base every time; therefore, the long-term good sealing performance is maintained, and the service life of the ball valve is prolonged.
Description
Technical field: the utility model relates to a kind of self-adjusting valve seat globe valve.
Background technique: ball valve as a kind of compact structure, open and close the pipe-line transportation system that valve rapidly is widely used in various fields.But, common ball valve is after long-term the use, often find that sealing surface of seat produces local uneven heavy wear, produce leakage down to the ball valve sealing decreased performance, trace it to its cause, be the moment of just having opened whenever valve, the high speed MEDIA FLOW of generation is washed away the valve seat part sealing surface consumingly, causes the sealing surface of seat concentrated wear and causes leaking.This uneven wear shows more obviously in inside nominal diameter greater than the ball valve of 300mm.And on the other hand, ball valve uses under some badness for a long time, and the sealing surface of seat periphery produces sediments, and the sediments of these bondings also will make the sealability of ball valve descend, and this is an one.Two also there is another problem in it for common ball valve, and when promptly ball valve is closed, the pressure of pipeline medium will directly act on valve rod.When ball valve was opened, valve rod not only bore torsional shearing stress like this, and bore the flexural stress that the pipeline pressure medium produces, so that the common ball valve valve rod cross section and the keying moment of ball valve drive unit all design, select greatlyyer.
Summary of the invention: the new purpose of this practicality is for solving the problems referred to above that existing ball valve exists, providing a kind of and can keep good seal performance, keying light self-adjusting valve seat globe valve rapidly for a long time.
The purpose of this utility model is achieved in that the self-adjusting valve seat globe valve still comprises valve body, ball core, is located at the valve rod of the valve seat that seals between body cavity passway and the ball core and drive ball core rotation carrying out valve opening and closing, it is characterized in that: valve seat is located between the body cavity ball core movingly, be provided with the valve seat driving mechanism between ball core and the keying valve seat, the every keying of ball valve once, this drive mechanism valve seat is to angle of fixed-direction rotation.
The ball core of above-mentioned self-adjusting valve seat globe valve can also be arranged with annular ball core supporting base outside the rotary axle box of two ends up and down movingly.
Adopt the self-adjusting valve seat globe valve of said structure, ball valve opens and closes each time, valve seat is all to angle of fixed-direction rotation, both sealings each time of ball valve, the relative contact position of ball core and valve seat all is different, this design makes ball valve after long-term the use, the sealing surface uniform wear, valve seat still can keep sealing reliably, simultaneously, and when service condition is abominable, sedimental generation can be smashed or prevent to rotatablely moving of valve seat, this structural design has solved valve seat uneven wear and sealing surface periphery sediments sticking problem effectively, keeps long-term good seal performance, thereby has improved the working life of ball valve.Second has increased the design of ball valve ball core supporting base, makes valve rod not bear line pressure.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings:
Structural representation when accompanying drawing 1 is opened for the utility model embodiment;
Accompanying drawing 3 is the closing structure schematic representation;
Accompanying drawing 4 is the valve seat construction schematic representation;
Accompanying drawing 5 is the valve seat side sectional view;
Accompanying drawing 6 is the pawl side sectional view.
Specific embodiment: as shown in Figure 1, this self-adjusting valve seat globe valve still comprises valve body 6, ball core 1, be located at two valve seats 3 that seal between valve body 6 bore passages mouths and the ball core 1, be that with existing ball valve difference the valve seat 3 of this self-adjusting valve seat globe valve is located at valve body 6 bore passages mouths movingly, valve seat 3 is ring and is made by sealing envelope material, the outer ring of valve seat 3 close neighbour's ball cores 1 one sides evenly is provided with 24 hook tooths 8, the direction of the hook tooth 8 of two valve seats 3 is preferably consistent, the number of hook tooth 8 and height are relevant with the angle of rotation each time, ball core 1 upside sphere is provided with a pair of ratchet 2 symmetrically, according to angle of swing also can be a pair of incessantly, the axis of passage is perpendicular in line between the ratchet 2 and the ball core 1, the ball core is provided with axle sleeve 9 in the center, two ends about in the of 1, axle sleeve 9 overcoats are established ball core supporting base 5 movingly, the external diameter of ball core supporting base 5 cooperates with valve body 6 inner chambers shoulder rank, help the effect of pipeline medium is passed on the valve body 6, reduce torsional shearing stress valve rod 7.
